I had a small fleet of 10 AI mining ships.
The sector was pretty much mined out so they were all clumped together around the last few asteroids. I was nearby in my ship.
Pirates warped in.
I ordered all of them to escort me to jump out, pirates got in range when I jumped away.
Turns out all my AI ships were left behind, so I jumped back.
AI miners were in mining range of pirates and started attacking them.
Managed to dealt with the pirates without losses, but:
One of the miners most likely accidentally hit another.
Suddenly ALL the AI miners started shooting at each other.
Before I could order them all to escort me so they'd stop sghooting I lost four miners and two were basically floating cubes.
So yeah, it would be nice to have player owned AI be passive towards each other. Or just have a passive stance setting (unless there is one and I missed it).
